Had a quick scout about and cant believe how much involvement Yamaha have had on the car engine side of things. They are responsible for that stonking engine in the lexus gt sports car thing and numerous others in particular the sho v6 for had them make in the states. Rumours <not in the below article> state that they had buzzed it to 11000rpm and it held 8500rpm for a whole 24 hours.
